IMPROVEMENT IN LOOMS.

Specification forming part of Letters Patent No. 122,976, dated January23, 187.2.

To all whom it may concern:

Be it known that I, JAW/LES WADE, of Palmer, in the county of Hampdenand State of Massachusetts, have invented a new and useful Improvementin Looms for weaving Brussels 0r tapestry carpets or other pile fabrics;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingmaking a part of this specification and to the letters of referencemarked thereon, in which- Figure l is a plan view of a loom for weavingBrussels or tapestry carpets or other pile fabric, having my inventionapplied, and showing the wire trough in a position close to the slide,and ready to have a wire drawn from its place in the fabric back intothe trough. Fig. 2 is a plan view of so much of the loom as relates tomy invention, showing the wire trough as having made its first movementfrom and parallel with the slide in the operation of transferring a wirefrom the fabric to the shed. Fig. 3 is a plan view of the same, showingthe wire trough as having made its next movement with the outer endthrown back toward the slide and the inner end thrown toward the lathe.Fig. tis a plan view of the same, showing the wire trough as having madeits next movement with the inner end thrown back again toward the slide.Fig. 5 is an end view of so much of the loom as relates to my invention.Fig. 6 is a front view of a loom having my invention applied. Fig. 7 isa side view of the cams and levers or arms which act nate the wiretrough, showing their relative position; and Fig. is a sectional view ofthe jointed rod attached to one end of the wire trough, the upper partof which forms one of the fulcrums upon which .the wire trough moves.

My invention relates to that portion of a loom for weaving Brussels ortapestry carpets or other pile fabrics, which operates to transfer thewires from the woven fabric to the open shed; and it consists of atrough placed upon the top of two upright levers which are pivoted upona rock-shaft at their lower ends, and which are operated to and fro bymeans of cams, each of which actuates a rod or arm attached to eachpivoted lever, and these are so arranged as to give the wire trough amovement to and from the slide, said movement bein gV partially paralleland partially oblique with reference to the slide. One or both of thepivoted levers is swiveled to the wire trough to permit of thisirregular movement; and another upright lev er, also pivoted to arockshaft at the lower end, is caused, by means of another cam and arm,to move the car-' riage to and fro upon the slide in the operation oftransferring the wire from the woven fabric to the shed, the carriage orthe slide, however, forming no part of my invention, except incombination with the wire trough llaving the partiallyY parallel andpartially oblique movement.

That others skilled in the art may be able to make and use my invention,I will proceed to describe its construction and its operation.

In the drawing, A represents the frame of a Brussels-carpet loom, and Arepresents the frame which supports the several parts of my apparatus,and which is attached to the main portion of the loom. D represents thewire trough, which is placed upon the upper ends of two upright levers,O and O', which levers are attached at their lower ends to the rockshaftb. Midway in the length of these levers are attached the two arms F andF', the arm F being attached to the lever O and the arm F to the leverO', 'these arms being support ed by the shaft l or in any convenientmanner. rPhe arm F has a projection, H, thereon, and the arm F theprojection H which projections are held in contact with the cams G andGr', preferably by means of springs or weights. These cams are rmlysecured to the rotating shaft I, and their form and relative positionwith each other are shown clearly in Fig. 8, the irregular form of thecam G being shown at ,the dotted line and by the numerals l, 3, 4, and5, and the irregular form of the cam G by the continuous line and thenumerals l, 3, and 2, the remaining portions of both cams being' similarin form. U represents the slide, along which moves the carriage N, towhich is secured any desirable device for withdrawing and inserting thewire. llhis carriage is caused to move to and fro along the slide C bymeans of the upright lever L secured at the lower end to a rock-shaft,L', to which motion is communicated by means of .the short arm Kattached to said shaft, the longer arms K and Q and the cam R operatingagainst the projection s. Both of the latter are shown in dotted linesin Fig. l. This oscillating movement of the rock-shaft L may be given inany other desirable manner. M represents the position of the reeds inthe lathe. The upright lever O is swiveled to the wire trough l),preferably by means of a joint shown in Fig. 8, in which O representsthe upper part of the lever O', having a cylindrical recess, f, therein,and a transverse hole, f', opening into the side of the recess. Theupper end of the lower part of the lever O has a projection, e, of aproper size to iit and turn freely in the recess f, and the saidprojection has an annular groove, e, thereon, so zthat, when theprojection e is inserted within its recess j and a pin inserted'throughthe hole ff passing into the annular groove e, the two parts O and 0 areconnected together, and yet so that the part O, to which is fixed thewire trough D, may turn upon its fulcrum O'. Any desirable form ofswiveled joint will answer the same purpose that will give the wiretrough the desired irregular movement.

Having thus described the construction of myinvention, I will proceed todescribe its operation. Motion. being given to the rotating shaft I, thecams G and G being attached thereto, they rotate in the directionindicated by the arrows in Figs. 5 and 7, and motion is also given atthe same time to the rock-shaft L, and the lever L attached thereto, bymeans of the tappet It and the connecting-arms Q K and Kf. When a wireis to be drawn from the fabric into the trough D the position of thetrough is in close proximity to the slide C, and the carriage N, withthe device for inovingthe wire attached thereto, is close to thewire-boX a. As the lever L and carriage N move out the device forwithdrawing the wire impinges against a wire head and draws the wirefrom the fabric into the trough, and the position of the carriage N isthen at the outer end of the slide. As the cams revolve the projectionsH and H', both, are forced back by springs or weights into the recessesmarked 3, as shown, Fig. 7, and thus far, as both cams are alike, thearms F and F both recede alike, and the trough D is caused to move backinto a posi tion parallel with the slide, as shown in Fig. 2. As thecams continue to revolve the projection H falls back still further intothe deeper recess marked 4 in the cam G, while the projection H isforced in the other direction by the point marked 2 on the other cam G',and the trough is thus brought into the oblique po-` sition shown inFig. IS, with the inner end carrind still further, the slide and theouter end carried nearer to it; and at the same time that the troughcommences this oblique movement the lever L commences to move inward,moving the carriage N along the slide, and the finger a', which projectsover the trough, and

which here illustrates the device for moving the wire in inserting itinto the shed, impin ges againstawire head, forcing the wire along also,the point of the wire being directed in an oblique direction, by theposition of the trough, into the open part of the shed. As the carriagewith its finger c passes along it is necessary that the trough shouldmove still further back to be within reach of the finger, and as thecams Gr and G revolve the projection His thrown forward into the recessmarked 5, which is not so deep as that marked 4, and the trough is' thusbrought to the position shown in Fig. 4 while the carriage N is nishingits movement toward the wire box a. The wire being now thrown into theshed, as the cams revolve the projection H is forced forward again fromthe recess 5 to the eXtreme circumference of the cam, and the trough isthus brought to its former position, shown in Fig. 1, ready to receivethe `next wire drawn from the fabric. It will be seen that by givingthis parallel and oblique movement to the wire trough I am enabled todirect the wire into the more open part of the shed and still have thetrough stand at such an angle dur` ing the operation of transferring thewire from the fabric to the'shed as to give the carriage the leastamount of work in moving the wire and decreasing the friction of thewire against the sides of the trough as it moves therein, and at thesaine time, to have the trough within reach of the device for movingthe' wire, thus preventing an increased amount of friction and wear andtear of machinery; and this is the object of my invention.

I am aware that various devices have heretofore been used to throw thewire into the open part of the shed 5 and I do not claim the attainmentof that object irrespective of my arrangement of the wire trough havingits parallel and oblique movement, and also its movement in connectionwith the movement of the carriage.

Having described my invention, what I do claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the carriage N with the wire trough D, having apartially parallel and partially oblique movement in the operation oftransferring a wire from the fabric to the open shed, substantially asdescribed.

2. I claim the wire trough D, moving upon two fulcrums O and Of, andoperated by means of the cams Gr and Gf, whereby a parallel and obliquemovement of the said trough is attained in the operation of transferringthe wire from the fabric to the shed, substantially as described.
